Grease Trap Regulations in Ohio

Overview

Ohio food service operators must follow FOG pretreatment rules under the Ohio EPA and local sewer utilities. Under Ohio's water pollution control laws, grease counts as a pollutant. A business cannot discharge any pollutant into state waters without a permit from Ohio EPA. The state combines administrative codes with local ordinances. Cities hold most of the day-to-day enforcement power. Major regional districts like the Northeast Ohio Regional Sewer District (NEORSD) run the wastewater plants and interceptor sewers. They protect water quality in Lake Erie, the Cuyahoga River, and other public waters. Ohio's combined sewer systems raise the stakes when FOG causes blockages and overflows. That makes interceptor installation, scheduled cleaning, and manifest records critical.

Governing Authorities

The Ohio Administrative Code sets the foundation for grease trap rules. Rule 3717-1-05.3 covers sanitation and equipment. Food service drainage systems, including grease traps, must be designed and installed under those code rules. The Ohio EPA's Division of Surface Water issues permits and sets statewide water quality standards.

Most enforcement happens at the local level through health departments and city wastewater plants. The most enforceable rules come from the local health department and the wastewater plant that serves your business. These bodies set cleaning frequencies, paperwork rules, and penalties.

The Northeast Ohio Regional Sewer District (NEORSD) runs three major wastewater plants on Lake Erie, the Cuyahoga River, and Rocky River. It serves 59 suburban communities and the City of Cleveland. The Metropolitan Sewer District of Greater Cincinnati (MSD) regulates food service customers in Cincinnati and Hamilton County through its Development Services and Commercial Waste groups. Columbus's Division of Sewerage and Drainage runs the FOG program inside the city. The Toledo-Lucas County Health Department handles plan reviews and inspections for food service kitchens. Butler County Water and Sewer Department may assess fines up to $10,000 per day, per violation, under Ohio Revised Code §6111.09.

Key Requirements

Where the local sewer authority requires it, you must install interceptors and separators. They keep oil, grease, sand, and other harmful substances out of the public sewer. Grease interceptors must receive drainage from fixtures and equipment with grease-laden waste in food prep areas. Place the trap so it stays easy to access for cleaning.

Installation and Sizing Requirements

• Small FOG producers usually need a grease trap sized to local plumbing code. Heavy FOG producers usually need a gravity grease interceptor sized to MSD's chart.
• Outside grease interceptors must hold at least 1,000 gallons in Butler County.
• Cincinnati may require grease traps or interceptors of at least 1,000 gallons. Sizing uses the MSD Grease Interceptor Sizing chart. The full kitchen, including the dishwasher, must drain to the interceptor.
• Hydromechanical grease interceptors, FOG disposal systems, and automatic grease removal devices must be sized to ASME A112.14.3, ASME A112.14.4, ASME A112.14.6, CSA B481.3, or PDI G101.
• Do not connect a food waste disposal unit to a grease interceptor.

Cleaning Frequency

• The most common standard is the "25% rule." Clean grease interceptors when the combined volume of FOG and settled solids reaches 25% of the trap's liquid capacity.
• Columbus requires cleaning once per calendar quarter, or before the trap reaches 25% — whichever comes first.
• Quarterly (every three months) cleaning is common, often tied to calendar quarters.
• Clean all grease interceptors at least twice a year. Some kitchens need to clean more often.
• For best results, clean a grease trap at least every 90 days.
• Akron requires regular cleaning. Most kitchens need service every 30 to 90 days, depending on use and grease load.

Record-Keeping and Manifest Requirements

• The Columbus City Code requires every food service kitchen to keep a Grease Interceptor Cleaning Log.
• Ohio law requires that all collected FOG and solids be disposed of off-site by a licensed hauler under state and federal rules.
• Food service kitchens must keep every manifest that documents grease waste removal.
• Kitchens in MSD's area must register with MSD. Initial registration is covered in the grease trap review. Renew every five years. Update when ownership or operations change.

Fines and Enforcement

Ohio enforces FOG rules through state environmental law and local ordinances. Penalties vary widely by jurisdiction.

State-Level Penalties

Under Ohio Revised Code §6111.09, water and sewer departments may assess fines up to $10,000 per day, per violation. Fines can run back to the first known day of noncompliance. Under Ohio's water pollution control laws, a business cannot discharge any pollutant into state waters without a permit from Ohio EPA. Ohio EPA treats grease as a pollutant under those laws. Businesses without proper permits or regular cleaning are in violation and face penalties.

Municipal Penalties

Citations can run from hundreds to thousands of dollars per violation. Some city codes set fines above $2,000. If a blockage happens, facilities may have to pay for city cleanup, extra inspections, and admin fees.

Enforcement Mechanisms

Neighbors or customers may spot grease on buildings, in parking lots, or in nearby waterways. They can report it to Ohio EPA or the health department. Inspectors may then trace the grease back to the restaurant and require cleanup. In severe cases, health departments can issue orders that disrupt business operations until the issue is fixed. Local sewer districts run regular inspections. They can require pretreatment permits with specific discharge limits.

Major City FOG Programs

Columbus FOG Program

Columbus identified FOG buildup in sanitary sewers as a leading cause of blockages. Greasy waste enters the sewer from homes, food service kitchens, and industrial sources. The Columbus Division of Sewerage and Drainage enforces FOG rules through the city's pretreatment program. Columbus requires grease trap cleaning once per calendar quarter, or before the trap reaches 25% capacity — whichever comes first. The Columbus City Code requires every food service kitchen to keep a Grease Interceptor Cleaning Log. Kitchens must use licensed haulers for waste removal and disposal.

Cincinnati MSD FOG Program

The Metropolitan Sewer District of Greater Cincinnati's Development Services and Commercial Waste groups regulate food service customers in Cincinnati and Hamilton County. Food service kitchens fall under MSD requirements per Article XV of MSD Rules and Regulations. They must also meet any Building or Health Department rules from the city or township. Small FOG producers usually need a grease trap sized to local plumbing code. Heavy FOG producers usually need a gravity grease interceptor sized to MSD's chart. Kitchens must register with MSD and renew every five years. The district publishes detailed sizing charts. It requires kitchen plumbing plans during the grease trap review.

Cleveland/NEORSD Service Area

The Northeast Ohio Regional Sewer District runs three major wastewater plants and related water pollution control facilities on Lake Erie, the Cuyahoga River, and Rocky River. It serves 59 suburban communities and the City of Cleveland. Project Clean Lake is a 25-year control program to cut combined sewer overflows in NEORSD's service area. NEORSD enforces FOG rules through its pretreatment program. Kitchens must install properly sized interceptors and keep regular cleaning schedules. The service area covers most of Cuyahoga County and parts of Summit and Lorain Counties. Local health departments help with enforcement.

Akron FOG Program

Akron businesses, especially restaurants, food processing plants, and commercial kitchens, must follow strict local rules on grease trap maintenance. The Akron Water Reclamation Facility's pretreatment program enforces those rules. Akron requires regular cleaning. Most kitchens need service every 30 to 90 days, based on use and grease load. The Summit County Public Health Department helps with enforcement. Food service kitchens must keep detailed records and use licensed haulers.

Frequently Asked Questions

How often do I need to clean my grease trap in Ohio?

It depends on your location and trap size. Columbus requires cleaning once per calendar quarter, or before the trap reaches 25% capacity — whichever comes first. The most common rule is the 25% rule: clean when FOG and settled solids reach 25% of the trap's liquid capacity. Most cities require quarterly cleaning (every 90 days) at minimum. High-volume kitchens may need monthly service. Check with your local health department and wastewater plant for the exact rule, since most enforcement is local.

What records must I keep for grease trap maintenance?

The Columbus City Code requires every food service kitchen to keep a Grease Interceptor Cleaning Log. Food service kitchens must keep every manifest that documents grease waste removal. Ohio law requires that all collected FOG and solids be disposed of off-site by a licensed hauler under state and federal rules. Keep cleaning service receipts, waste manifests showing proper disposal, and inspection reports for at least three years. Many local health departments inspect kitchens and ask for these records.

Can I install a garbage disposal in my commercial kitchen?

Do not connect a food waste disposal unit to a grease interceptor. If a food waste disposer connects to a grease interceptor, a solids interceptor must separate the discharge first. Solids interceptors and grease interceptors must be sized and rated for the disposer's discharge. Emulsifiers, chemicals, enzymes, and bacteria are banned from the disposer. If you plan to install a disposal, talk to your local health department and sewer authority first. You will need extra pretreatment equipment.
